REGISTER FOR FLUES.

SPECIFICATION forming part 6f Letters Patent No. 524,310, dated August14, 1894.

Application filed May 8, 1893. Serial No. 473,391. (No model.)

To all whom it may concern:

Be it known that I, ANDREW J. COHEN, of the city of Philadelphia andState of Pennsylvania, have invented a certain new and usefnlImprovement in Registers for Flues; and I do hereby declare thefollowing to be a full,

clear, and exact description thereof, reference being had to theaccompanying drawings, forming part of this specification.

My invention has relation to registers for hot and cold air flnes, andconsists in the de-. vlce hereinafter particularly described andclaimed.

The object of my invention is to produce, as a new article ofmanufacture, an ornamental register box the face and inner flanges ofwhich are formed integral of earthenware, or other like material, moldedand formed from a plastic state, and in which the mate rial composingthe face of the register is susceptible of receiving a glazed finishupon its outer surface without the application of foreign material tothe face for the purpose of producing said glaze as in registersheretofore known, which glaze as heretofore provided is liable to chip0d by slight knocks.

A further object is to provide in earthenware register boxes metallicshutters, preferpearance thanin the ordinary metallic register boxes,the face, for instance, may be molded to follow the pattern in a tiledwall in whichit is to be placed, if desired.

Relief effects may be produced in the plastic face of my improvedregister box which structed much thicker than the like parts of a metalregister, to give the requisite strength,

an increased radiating surface is presented.

The earthenware, or like material, thus operates functionally toassistdn diffusingthe heat. The nature of the construction of myinvention allows of it's-production at a consider- 6o 'ably less costthan the register boxes heretofore invented, and will permit of itsbeing placed upon the market at a much reduced price. 1 p

In the accompanying drawings, Figure l is a front perspective view ofthe earthenware register box, representing a plain, yet ornamental,design of glazed face. Fig. 2 is a rear perspective view. Fig. 3 is anenlarged detail view in longitudinal section, through the center. I

The face, A, is formed integral with the rectangular flanges, a, theupper andlower of which flanges are provided with orifices for thereception of the' pivots, p, provided on the slats, b, which pivotsextend into or through the said orifices. The slats, b, are preferablyformed of flexible sheet metal, and have provided at either end the saidpivots, p; the pivots are secured upon the slats, b, by any suitablemeans, for instance, in the manner shown in the drawings, wherein theinner end of the pivot is recessed for the reception of the end of theslat and is secured thereon centrally in a vertical position by rivets,or by other suitable means; the pivots, however, may. be constrncted andsecured by any well known means. When flexible slats are employedv theycan be readily secured into position within the box, formed by theflanges, after 0 the pivots, p, have been provided on the said slats bysimply slightly bending the slat, as illustrated in Fig. 2; where,however, rigid slats are employed, they may be readily secured inposition by inserting into the orifice 5 oted arms or levers secured tothe slats and 10) pivotally connected to a cross arm may be employedwithin the box as a means for open- 1ng and closing the slats or valves,1), from without, such for instance as shown in Fig. 2.

In register boxes, as ordinarily constructed,

the face, being severable from the inner' the upper or other flanges aspring, 5, having the tension tending outwardly from the face of theflange, said spring being constructed preferably, as shown in thedrawings, of a loop of wire with the loopextending outwardly from theouter face of the flange toward the face of the register and its innerends secured through an orifice provided in the flange and bent downthereon; the lower arms may be countersunk in the inner face of theflange, or not, as desired. It is clear that other forms of spring mayalso be employed to accomplish the same purpose, such as a plate springscrewed or riveted to the flange.

As the register box is inserted in the flue or orifice in the wall thespring, 5, will become depressed in coming in contact with the walls ofthe flue and tending to spring outward will hold the box firmly inposition, while it is also clear that, by the exercise of little force,the box can, when desired, be readily removed by pulling outwardly.

Another and equally desirable method of securing my earthenware boxinthe wall consists in applying mortar or plaster between the inwardlyprotruding flanges of the box and the sides of the orifice in the wallin which it is inserted; the mortar or plaster when dry will form asolid union between the integral earthenware flanges of the register boxand will makeit adhere so strongly to the Wall that it will be almostimpossible to detach it therefrom. The register box thus practicallybecomes integral with the wall. This function of the earthenware flangewhich affords a positive union also affords a most ready means ofsecuring the register in the wall.

In enameled register faces, as heretofore employed, the glazing orenameling has been applied to the outer surface of a metallic registerface. This enameling, by reason of its construction and method ofapplication, is

liable, when subjected to knocks such as register faces, by reason oftheir exposed position, are constantly liable, to crack and fall off inplaces, disfiguring the face of the register. In my invention thisobjection is overcome, as the enamelingor glaze, which is produced byany Well known method of glazing earthenware, being integral with theface itself, cannot crack or peel off by any ordinary shock or blow; andthe register face, being integral with the inner flanges, obviates thenecessity of the use of screws or bolts which usually protrude throughthe face, and consequently disfigure to a greater or less extent theappearance of the face.

In my improved construction the number of parts necessary to form theentire register box, with valves, is reduced to a minimum, and the workrequired in the assemblement of the parts is also reduced materially,allowing the production of the most ornamental registers at acomparatively small cost.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

' 1. An earthenware molded register frame consisting of a perforatedface extending across the entire frame and side and end flanges moldedto the rear of the face at an angle to the line of the face the wholeformed from plastic material in one integral piece,

substantially as described.

2. An earthenware register frame consisting of a perforated faceextending entirely across said frame and inner side and end flanges atan angle to the line of face and formed integral with the said faceconstituting theinner box molded from material while in the plasticstate and metallic slats pivotally secured in the said boxing, and meansfor opening and closing said slats, substantially as described.

In witness whereof I have hereunto set my hand this 5th day of May, A.D. 1893.
